[Electroneurographic findings in cyclist's palsy (author's transl)].
The electromyographic and electroneurographic findings of a patient with cyclist's palsy of both hands are reported. The electrophysiological results show a compression syndrome of the deep palmar motor branch of the ulnar nerve without involvement of the hypothenar branches (Fig. 2a, b). Two more types of cyclist's palsy should be differentiated reviewing the literature: 1. a compression of the ulnar nerve at the wrist a lesion of the superficial branch, and 2. a compression of the deep motor branch including the hypothenar branches. As in the literature described probably exists a further type with an isolated lesion of the superficial branch of the ulnar nerve; but there are no electroneurographic findings reported.
